It was so early recognized as characteristic of Chopin that a magnificent example may be seen at the end of Schumann's little tone-portrait of him in the Carnaval: a very advanced Wagnerian passage on another principle constitutes the bulk of the development in the first movement of Beethoven's sonata Les Adieux; while even in the " Golden Age " of music, and within the limits of pure diatonic concord, the unexpectedness of many of Palestrina's chords is hardly less Wagnerian than the perfect smoothness of the melodic lines which combine to produce them.
Her favorite sonata bore her into a most intimately poetic world and the look she felt upon her made that world still more poetic.
Classical and modern chamber-music in the sonata style consists mainly of string-quartets for 2 violins, viola and violoncello; string-trios (rare, because very difficult to write sonorously); pianoforte-trios (pianoforte, violin and violoncello); pianoforte-quartets (pianoforte with string-trio); pianoforte-quintets (pianoforte with string-quartet); string-quintets (with 2 violas, very rarely with 2 violoncellos), and (in two important cases by Brahms) stringsextets.
Moreover, the higher problems of rhythmic movement in the classical sonata forms are far beyond the scope of academic teaching; which is compelled to be contented with a practical plausibility of musical design; and the instrumental music which was considered the highest style of art in 18 3 0 was as far beyond Wagner's early command of such plausibility as it was obviously already becoming a mere academic game.
But with Wagner, just as there are people who have never tried to follow a sonata but who have been awakened by his music-dramas to a sense of the possibilities of serious music, so there are lovers of music who avow that they owe to Wagner their appreciation of poetry.
From the far side of the house through the closed doors came the sound of difficult passages--twenty times repeated--of a sonata by Dussek.
Least of all can it conduce to the formation of sound critical standards for the new instrumentation which is now in process of development for the future forms of instrumental music. These, we cannot doubt, will be as profoundly influenced by Wagner as the sonata style was influenced by Gluck.
